What is the best way to thaw a prime rib?
Cover your prime rib (tightly sealed) in cold tap water. Depending on the weight, you may have to change the water every 3 – 4 hours. I do this with my turkey every Thanksgiving Eve. I place it in an ice chest the night before. It is perfectly thawed by the time it ready to go in the oven. My turkey usually weighs 20 – 24 lbs and it about 12 hours. A prime rib may only take 4 – 7 hours.
